ABSTRACT

A new and distinct Hybrid Tea Rose plant having attractive light pink flowers.

CROSS-REFERENCE TO RELATED APPLICATION(S)

This Patent Application claims priority of European Patent Application No. 2000/1930, Certificate No. EU7944, dated Jul. 16, 2001 and Patent Application filed in The Netherlands, Application No. ROO2714, Certificate No. 19668, dated Apr. 6, 2001.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the Hybrid Tea rose class Botanical Classification Rosa L., male and female parents are unknown. The varietal denomination of this new rose is named ‘Ruivonk.’ The new variety was grown from a seed in The Netherlands.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by this new variety which distinguishes it from all varieties of which I am aware is its attractive flowers and large vase life.

Reproduction by propagation by cuttings of the new variety as performed in De Kwakel, The Netherlands shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagation.

BRIEF DESCRIPTION OF ILLUSTRATION(S)

The accompanying illustrations show a typical specimen of the new variety depicted in color as nearly true as is reasonably possible to make the same in a color illustration of this character.

In FIG. 1, there is shown a young shoot 1; compound 3, 5, and 7 leaves, 2, 3 and 4; a stem segment without leaves 5; a flower bud after sepals open 6; flowers in different stages of development, 7, 8 and 9; and reproductive organs 10, 11 and 12.

FIG. 2 shows a bloom of the new variety.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of the new variety with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C). The terminology used in color description herein refers to plate numbers in the aforementioned color chart. Phenotypic expression may vary with light availability, environmental and cultural conditions.

The following observations are made of 9-month old plants grown in a greenhouse in De Kwakel, The Netherlands during September from a rooted cutting.
